Background

日本のPPP/PFI制度は、優先的検討規程の策定拡大、スモールコンセッション・プラットフォームの設立、地域プラットフォーム協定制度の展開など、急速に整備が進んでいる。しかし「制度の存在」と「制度の機能」の間には構造的な乖離が存在する。本研究室では、内閣府・総務省・国交省の公開データと実務者の知見を交差させ、制度が意図した通りに機能しているか、どこに空白地帯があるかを定量的・構造的に分析する。

The Structural Gap in Priority Review Regulations — Behind the 82% Adoption Rate Lies a System That Doesn't Work

Japan's Cabinet Office has promoted Priority Review Regulations for PPP/PFI adoption, achieving an 82.1% adoption rate among cities with 200,000+ residents. Yet a structural gap exists between adoption and actual implementation. This analysis cross-references population-stratified data, Ministry of Internal Affairs surveys on institutional hollowing, and pioneering cases to quantify why regulations exist but fail to function.
